        By default, creates a multipart/mixed message, with proper

        _subtype is the subtype of the multipart content type, defaulting to
        `mixed'.
        
        boundary is the multipart boundary string.  By default it is

        _subparts is a sequence of initial subparts for the payload.  It
        must be an iterable object, such as a list.  You can always
        attach new subparts to the message by using the attach() method.
        
        Additional parameters for the Content-Type header are taken from the
        keyword arguments (or passed into the _params argument).
